Large-cap stocks remained largely flat, with Adani Power emerging as the top gainer, rising by 1.68%.

The BSE100, MIDCAP, and SMLCAP indices all recorded losses, falling by 0.51%, 0.83%, and 1.0%, respectively. As the market continues to navigate these challenges, upcoming earnings reports from major players like Axis Bank and HDFC Life Insurance on October 15, 2025, will be closely watched.
